Definitions

  • One embodiment of this invention implements the coarse and fine delay sections in a SiGe ASIC (chip) and partitions the system such that random access memories (RAM's) and digital-to-analog converters (DAC's) are external to the ASIC.
  • RAM's random access memories
  • DAC's digital-to-analog converters
  • further advantages result from implementing the circuitry in fully differential current steering logic and differential analog amplifiers such that the chip draws a constant current independent of clock frequency. This minimizes on-chip transients that could introduce jitter in the output.
  • step 616 the combiner 412 selects one of the fine timing signal transitions according to the coarse timing signal 428 and outputs the resulting timing signal 436.
  • FIG. 16 is a timing diagram illustrating the details of the early/late (E/L) signal discussed above in connection with FIG's.9 and 12.
  • the E/L signal is used to position the fine delay pulse (FDP) anywhere in the coarse delay interval (also called a slot or bin) with 100%o coverage. Since the fine delay pulse rising edge can be anywhere in the coarse delay interval, there is some range of fine delay values that fall too close to the metastable range of the combiner fiipflop 1232 to yield accurate results.
  • two reclocked versions of the stretched CDP output of pulse stretcher 1204) are created. As illustrated in FIG. 12, an early version (E) is created by fiipflop 1212 on the falling edge of CLK. A late version (L) is created by fiipflop 1208 on the rising edge of CLK. Either the
